Identification and Apportionment of Release Sources of Particulate Matters in the Atmosphere

Abstract

Source apportionment of particulate matters in urban atmosphere is becoming important in air pollution control strategies. Two techniques are used for evaluating the source-receptor relationship. The one, which is called source-oriented model, starts with individual source data, and predicts the impact of the source at environment. Another is called receptor-oriented model and utilized for the identification and the apportionment of release sources using various data of particulates obtained at the environment.
This paper describes the characteristics and behavior of particles in urban atmosphere, and reviews the analyzing techniques for source-receptor relationship of particulate matters.
